Abstract

We analyze the properties of electroweak chiral effective Lagrangian with an extended gauge group. Right-handed gauge bosons affect electroweak observables by mixing with electroweak gauge bosons and . We discuss all possible mass mixing terms and calculate the exact physical mass eigenvalues by diagonalization of mixing matrix without any approximate assumptions. The contributions to oblique radiative corrections parameters STU from fields are also presented.
